The Soudan Mine targeted high-grade iron ore (specularite) for many decades and closed in the early 1960s. The site is now accessible to the public and underground tours are offered. Observed iron-rich lithologies in the Soudan Iron-Formation include specularite, jaspilite BIF, and magnetite BIF.

Uses of Hematite (Iron Ore) Hematite is the world's most important ore of iron. Although magnetite contains a higher percentage of iron and is easier to process, hematite is the leading ore because it is more abundant and present in deposits in many parts of the world.

15.1. Introduction. Iron ore lump, sinter, and pellets comprise the main burden of modern blast furnaces. However, sinter and pellets are now the dominant blast furnace burden, because the natural lump supply has declined dramatically due to depletion of the world's high-grade competent iron ore resources.

Specular hematite is the most common iron mineral in unaltered iron formation associated with chert and magnetite. In altered iron formation, red hematite and limonite are most common (Hotchkiss, 1919; Carr and Dutton, 1959). Botryoidal hematite is also found. 2. Eastern Gogebic range: Martite (Mann, 1953). 3.

Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.
